TENSION-REGULATOR FOR SPINNING OR TWISTING MACHINES.-

SPECIFICATION forming part of Letters Patent No. 691,594, dated January21, 1902.

Application filedI'ebruary 15, 1901. Serial No- 47,480. (No model.)

To aZZ whom it may concern.-

Be it known that LARTHUR OEcIL BUTLER, a subject of the King of GreatBritain and Ireland, residing at Wollaston, in the county of Norfolk andState of Massachusetts, have invented a certain new and useful TensionRegulator or Governor for Spinning or Twisting Machines, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to a device in a spinning or twisting machineforregulating or governing the tension of the yarn as it passes from thedelivery-rolls through the traveler to the bobbin; and it has for itsobject to provide a simple and efficient means for producing saidresult.

According to the present'invention I am enabled to produce a strongerand more elastic yarn and a more uniformly-compact cop or bobbin thanhas heretofore been produced. Furthermore, by the use of'my inventionfiner counts may be spun than have heretofore been spun and a bobbin ofsmaller diameter used than has heretofore been used in machines of asimilar character. In addition my invention prevents the ballooning ofthe yarn, either when spinning or twisting.

The above-mentioned advantages and object of my invention will be morefully set forth and explained in the hereinafter-detailed description.

The invention consists, broadly, of a rotatable governor or regulatorattachment for spinning or twisting frames which is capable of an axialor up-and-down movement relatively to its shaft or axle under strain ofthe yarn, whereby the tension of the yarn may be regulated or governed.

The invention further consists of the novel features of constructionhereinafter set forth and described, and more particularly pointed outin the claims hereto appended.

.Referring to the drawings, Figure l is a side elevation of thepreferred form of my invention. Fig. 2 is a plan View of the same. Fig.3 is a plan of the under side, and Fig. at is a view of a verticalsection. of a modification .of my invention, and Fig. 6 is a plan viewof the same.

Like letters refer to like parts throughout the several views.

Fig. 5 is a viewring, and g the movable ring-rail, all of ordinary andusual construction tisarevolubledisk. kisahollowsplitspindle-engagingsleeve projecting from the nu der sideof said disk, and Z an uprightshaft or axle extending from the upper side of said disk.

The parts i, k, and Z are made of metal, preferably of steel.

m is a collar madeof suitable material and detachably connected withtlieupper end of the shaft or axle 1. T a

nis a revoluble or rotatable governor or regulator made,preferably,ofsteel and loosely mounted on the shaft or axle Z and adapted to rise andfall upon said shaft under strain of the yarn-that is to say, the saidgovernor is capable of an axial 'orIup-and-down movement relativelytoits shaft or axle under strain of the yarn.

0 0 denote guides or eyes on the governor or regulator, through one ofwhich the yarn passes.

The above-mentioned device is detachably connected with the spindle, asillustrated in Figs; 1 to 4, inclusive, the hollow split sleeve It beingconstructed of a suitable size and having such a degree of resiliencythat it will fit onto and be held firmly on the top of the spindle, orit may be detachably connected with the bobbin in the same manner thatthe modification is connected, as shown in Fig. 5.

The'mode of operation of the above device in so far as it has notalready been disclosed is as follows: The yarn passes from the delivery-rolls and thread-guide (not shown) through the guide 0, thenceover and upon the periphery or edge of the disk 1 and thence through thetraveler to the bobbin; When the spindle and bobbin are rotated, thedisk z'is also rotated, the pull of the yarn upon the traveler causingthe latter to revolve upon the race of the ring. The governor or reguinclose contact with the yarn assists or aids the traveler in its rotarymovement. \Vhen the spindle and bobbin are rotated at any rate of speed,the pull of the yarn causes the governor or regulator '17, to rise, theedge or periphery of the disk 2 acting as a fulcrum. The greater thepull or strain of the yarn the higher the governor will rise on its axleZ, and when the tension becomes slack for any reason the governor willfall, the rising-and-falling movement or up-and-down movement occurringbetween the disk 71 and the collar m. It is obvious that by this meansthe tension on the yarn is constantly regulated and governed, andthereby an even tension on the same is maintained, whereby a strongerand more elastic yarn and a more uniformly compact cop or bobbin areproduced. Furthermore, the yarn by being held continually in contactwith the edge of the disk 2' (and the latter revolving with the spindle)imparts to the traveler a rotary motion quite apart or in addition toits being dragged around by the bobbin. Thus much of the strain upon theyarn is relieved, and for this reason and the fact that the regulator orgovernor readily yields to any extra strain that would otherwise breakthe yarn finer counts may be spun 1 the spindle whenever it becomesnecessary to and a bobbin of smaller diameter used.

In the spinning or twisting machines the yarn as it is being built up onthe bobbin has a tendency to balloon at a point intermediate thetraveler and the delivery rolls. This tendency to balloon is obviated bymy device, for besides being held in against the disk the slack is takenup by the weight of the governor it, thus reducing the tendency toballoon to a minimum.

I believe that I am the first person to produce a governor or regulatorfor regulating the tension and for maintaining an even tension upon theyarn and one that acts automatically under stress of the yarn.

Referring to the modification set forth in Figs. 5 and 6, the disk 19 isthe rotatable governor or regulator, made, preferably, of metal andloosely mounted on the axle Z, likewise preferably made of metal andadapted to rise and fall or to move up and down on said axle understrain of the yarn. This up-anddown movement takes place between thecollar m and the rotatable ring q, made, preferably, of metal, which isloosely mounted upon the axle Z and rests upon the collar m, secured tosaid axle. The ring q is provided with the guides or clips o 0", throughone of which the yarn passes. The lower portion of the axle Z terminatesin the split sleeve is, which is slightly tapered at the bottom and ofsuch a size and having such a degree of resiliency that it will fit intoa. recess in the top of the bobbin and beheld firmly in frictionalcontact with the bobbin. The spindle is shown as projecting into thesleeve it; but it is not necessarily held by the latter. The

mode of operation of this modification is substantially the same as thatof my preferred form of invention, except that the modification is shownas being detachably connected with the bobbin, although it mightobviously be detachably connected with the spindle, as in Fig. 1, andexcepting that in the modification the governor-disk p and the ring (1are both loosely mounted on their axle, whereas in my preferred form ofinvention only the governor is loosely mounted upon its axle, the diskL' forming a part of or being rigidly attached to the axle.

In the modification the yarn passes from the delivery rolls and threadguide (not shown) over and upon the edge of the governor-disk p, thencethrough the guide 0, and thence through the traveler to the bobbin. Inthe modification the strain of the yarn when the spindle and bobbin arerotated causes both the governor-disk p and the ring q to rotate and thegovernor-disk to rise and fall in precisely the same manner that thegovernor n rises and falls. The principle of the invention, however, inboth forms thereof is substantially the same, as .will be readily seenwithout further description.

Both forms of my invention being detachably connected either with thespindle or bobbin the latter may be easily removed from remove it.

What I claim, and desire to secure by Letters Patent, is

1. An attachment for spinning or twisting frames, comprising a shaftprovided with means for attaching it to a revoluble body, and a governoror regulator, through which the yarn is passed to the bobbin, m'ountedupon said shaft loosely and capable of upand-down movement on said shaftas the latter revolves, substantially as described.
